A Primer on EV Charger Connector Types

With electric vehicles (“EVs”) poised to replace conventional gas-powered cars over the next few decades, EV chargers are going to be much more commonplace. Rather than internal combustion engines, EVs rely on rechargeable lithium-ion battery packs for power. While you can fill up a conventional internal combustion engine vehicle at virtually any gas station, there is currently no universal EV charging connector.

Some regions use a specific charging connector while, in other cases, EV makers choose to use a specific proprietary connector regardless of what is common to the region. Charging an electric vehicle is similar to charging a mobile phone or a laptop: one end of the charging cable is plugged into the car while the other is plugged into the charge point.

There are three types of charging connectors, which is the end that connects the cable to the vehicle.

Sort 1 connectors are used mainly in Asian countries, although they are also used in North America for low voltage charging. This charging connector has five pins consisting of three large pins and two smaller ones, and usually has a power rating of 3.7kW to 7kW. It can add 12.5–25 miles of range per hour assuming the electric vehicle is equipped with a 60kWh battery capable of 200 miles of range.

Sort 2 connectors, which were popularized by Tesla superchargers, are the most widely used EV charging connectors. There are two versions of the Sort 2 connector, an AC model that consists of five large pins and two smaller ones, and a DC model, which has the same design as the AC model with an additional two large pins. Thanks to three power rating phases — 3.7kW, 7kW, and 22kW — a Sort 2 connector can add either 12.5 miles, 25 miles, or 75 miles per hour of charging.

Sort 3 charging connectors are the least used of all the three varieties. They have seven pins and, unlike the first two types, they are equipped with a weather protective security shutter that allows them to withstand heavy rainfall.

In terms of charging speeds, EV drivers have three options to choose from: sluggish, which is the slowest, quick and fast. However, note that how fast your EV can charge will also depend on its make and model. Some EV models can recharge in as little as 30 minutes while others simply aren’t designed to charge that fast.

With companies such as Ideanomics Inc. (NASDAQ: IDEX) focused on facilitating the switch to electric mobility and improving the technologies that support the sector, chances are that EV chargers are set to get better and better as the years roll by.
